It's clear _to us_ because when we think about such things, we think in Newtonian terms. I'm not at all sure it would have been clear to people in the middle ages; when you throw a ball, it whizzes by so fast, it's hard to be sure how it's actually moving. -- http://mail.python.org/mailman/listinfo/python-list
